SUMMARY OF THE INVENTION The present invention provides a water level detecting means for detecting a water level in a bathtub, a water level setting means for setting a water level in the bathtub, and a plurality of displays corresponding to the water levels set by the water level setting means. A control device for controlling the hot water supply to the bathtub by comparing the detected water level of the water level detecting means with the set water level of the water level setting means, and displaying the set water level of the water level setting means on the plurality of display elements. When the water level setting means is operated, the control device displays the set water level before the setting operation and the set water level after the setting operation in different lighting states on the plurality of display elements.

Further, a water level detecting means for detecting a water level in the bathtub, a water level setting means for setting a water level in the bathtub, a plurality of display elements corresponding to the water level set by the water level setting means, and a detecting means for the water level detecting means A control device for controlling the hot water supply to the bathtub by comparing the water level with the set water level of the water level setting means, and for displaying the set water level of the water level setting means on the plurality of display elements, the control device comprising: When the operation is performed, the set water level after the setting operation is lit on the plurality of display elements, and the set water level before the setting operation is blinked on the plurality of display elements for a predetermined time.

[0007]

With the above-described structure, when the bath is automatically operated, if a water level setting key serving as a water level setting means of a remote controller is pressed as a bathtub water level setting, a display element having a lamp configuration is turned on. The initial setting of the water level can be determined by the lighting of the display element of the preset water level and the lighting of the display element by the water level setting key which is just pressed.

In this case, when a new display element is turned on in response to the water level setting key operation (current water level setting), the lighting of the display element which has been set so far is switched to blinking lighting.
Moreover, at this time, if the key pressing operation of the water level setting key is repeated a plurality of times within a predetermined time, the blinking of the first display element is kept as it is, and the lighting is shifted to another display element by the number of pressing times, It is now easy to determine the correlation with the water level.

On the other hand, for the bathtub, the water level detected by the water level detecting means is compared with the water level set by the water level setting means to control the hot water supply and to perform a desired filling.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings of the embodiments.

FIG. 1 and FIG. 2 show a bathtub hot water supply apparatus having a bath watering function having a bath watering function. Reference numeral 1 denotes a remote controller for a water heater having a bath watering function (not shown).
The display section of the operation panel 1a of the remote controller 1 has a bathtub pattern 2
And a plurality of display elements 3 for displaying a water level are vertically arranged on the lateral portion thereof, and a clock display section 4, a reheating display section 5, a bath temperature display section 6, and a hot water supply temperature display section are provided. 7
A water level setting key 8 serving as a water level setting means is provided near the bathtub pattern 2 of the operation unit, and a time adjustment key 9, an automatic operation switch 10, and a bath temperature serving as an up / down key. A key 11, a hot water supply temperature key 12, a switch 13 for additional heating, and the like are arranged. Further, the microcomputer 14 serving as a control device has the water level setting key 8 on the input side.
And an operation section of an automatic operation switch 10, a bath temperature key 11, a hot water supply temperature key 12, an additional heating switch 13, a hot water supply temperature sensor 15, a water flow switch 16, and a bath pouring counter 1.
7 are provided, and a pouring valve 18 and a gas main valve 19 are provided on the output side.
Hot water supply gas proportional valve 20, gas burner 21, bath pump 2
2, an ignition device 23, a three-way valve 24, a water level detecting means 25, and a water level display element 3 serving as the display section, and the like.
With these configurations, a bathtub water heater is provided.

Next, the bathtub water level setting will be described with reference to the flowchart shown in FIG. 3. First, when the water level setting key 8 is pressed as a bathtub water level setting process, the automatic bath operation is turned on in advance.
, The microcomputer 14 determines whether or not there is a water level setting input. In the first water level setting key operation, there is an input (because the previous water level setting has been performed), and since the 10-second timer is not working, the current water level setting value is the current water level setting (Initial water level setting) is stored in the memory. Then 10
The timer starts operating with the setting of the second timer. Here, since there is no water level UP flag at first, the process proceeds to the right to determine whether the current water level setting is MIN (whether the water level is at the lowest position). For example, if the lighting position of the display element for the initial water level setting is not the lowest, the current setting water level is 1
The rank becomes smaller, the display element corresponding to the initial water level setting starts blinking, and the display element corresponding to the current water level is turned on (see FIG. 4).

Next, in a state where the first water level setting key operation is performed and 10 seconds have elapsed, the display element of the initial water level setting which is the display element corresponding to the initial water level setting is turned off, and the water level UP flag is reset. Only the display element corresponding to the currently set water level lights.

After the first water level setting key operation, one
If the second key operation is performed within 0 seconds, the display element corresponding to the initial water level setting is blinking, the display element lit by the first water level setting key operation is turned off, and the display element at a lower position is turned off. It will be lit. Of course, the current water level setting is one rank smaller.

Further, when the water level setting key is further operated and the current water level is at the minimum value (MIN), the water level UP flag is raised and the current water level is increased by one rank, and one level above the lowest display element. Lights up. When the operation of the water level setting key 8 is further repeated, the currently set water level increases by one rank, and the lighting of the display element moves upward by one. Of course, if the currently set water level is MAX, the water level UP flag is reset, and thereafter, the currently set water level decreases by one rank, and the lighting of the display element shifts downward. When 10 seconds have elapsed since the last key operation was stopped, the initial water level setting display element is turned off and the water level UP flag is also reset. This means that there is no water level UP flag at the time of the first key operation.

Here, the pouring of the bathtub 26 is as follows.
As shown in FIG. 5, the hot water flowing out of the hot water supply heat exchanger 27 heated by the ignition of the gas burner 21 flows into the bathtub 26 via the bath pouring counter 17. The water level stored in the bathtub 26 is detected by a water level detecting means 25 serving as a water pressure sensor, and a predetermined amount of molten metal is poured under the control of the microcomputer 14.

[0017]

As described above, the bathtub hot water supply apparatus of the present invention uses a plurality of display elements to display the water level using a remote controller or the like, and also displays two levels corresponding to the original water level setting (initial water level setting) and the current water level setting. One display element is turned on, and one display element (display element of the original water level setting) is switched to blinking, and the display element corresponding to the current water level setting is turned on to determine the correlation between the current water level and the original water level. To ensure. When the water level setting is sequentially changed within a predetermined time (within 10 seconds of one key operation), the display element corresponding to the current set water level is turned on for each operation while the original display element is kept blinking.
That is, it becomes clear how many steps the current setting position has been changed. Further, after a predetermined time of the setting operation has elapsed (after confirmation), the original blinking display is turned off, so that useless display is eliminated.
